发布时间：2018-09-18 10:45
【摘要】：为了研究车辆合流过程需要的平行式加速车道长度问题,在分析车辆合流过程的基础上,考虑道路运行和设计属性、驾驶员属性、车辆属性及合流车辆汇入过程随机属性,结合运动学模型和可接受间隙理论模型,以汇入过程随机属性为突破口,根据合流车辆的相对位置,建立了基于动态汇入过程的平行式加速车道长度计算模型。通过蒙特卡罗模拟进行仿真,将适宜百分位数的长度确定为加速车道长度,实现了模型的求解。最后通过案例分析介绍了模型的使用方法,案例结果大于规范推荐值,证明模型具有一定的适用性。
[Abstract]:In order to study the problem of parallel acceleration lane length in the process of vehicle convergence, the road operation and design attributes, driver attributes, vehicle attributes and random attributes of confluence process are considered based on the analysis of vehicle convergence process. Combined with kinematics model and acceptable gap theory model, a parallel acceleration lane length calculation model based on dynamic convergence process was established based on the random attributes of the confluence process as a breakthrough point and according to the relative position of the confluent vehicle. Through Monte Carlo simulation, the length of the appropriate percentile is determined as the length of the accelerated lane, and the solution of the model is realized. Finally, the application method of the model is introduced through the case analysis. The result of the case is larger than the recommended value of the standard, which proves that the model has certain applicability.
